“…There was no appreciable difference between the two subtypes of insomnia. Previous studies showed a significant association between insomnia and the prevalence of HT 9,[12][13][14] , but this is the first study to demonstrate that persistent insomnia may be a useful predictor of HT in a follow-up design.…”

“…A longitudinal database was accumulated from an employee health management center in a Japanese telecommunication company. Details of the process of annual health examination have been described elsewhere 13,14,16) . Briefly, the participants in the annual health examinations were asked to complete a structured questionnaire about their medical history, physiological and psychological complaints, and daily life.…”

“…The presence of DIS was defined by an affirmative answer ('always' or 'sometimes') to the question of "falling asleep with difficulty". That of DMS was defined by an affirmative answer ('always' or 'sometimes') to the questions on "awakening many times in the night" and "awakening once in the night and falling asleep again with difficulty" 13,14) . The results of crosssectional analyses suggested that DIS and DMS might be differently associated with the prevalence of HT 13,14) .…”

“…Age, body mass index (BMI), diabetes, smoking and alcohol drinking, and job stress were taken into account as potential confounding factors in the association between insomnia and HT 13,14) . BMI was categorized into four strata: ≤18.5, 18.6-24.9, 25.0-29.9, and 30.0≤ kg/m 2 .…”

“…We previously elucidated sociodemographic, lifestyle, psychological and physical factors associated with two subtypes of insomnia in Japanese male workers. After adjusting for confounding factors, difficulty initiating sleep (DIS) and difficulty maintaining sleep (DMS) were significantly associated with hypertension (HT) 13,14) . Similarly, several investigators reported a significant association between insomnia and HT 9,12) , but these findings were derived from cross-sectional analyses.…”

Marianna University School of Medicine-Insomnia is one of the most common complaints at worksites, as well as in the general population. This study aims to assess the effect of insomnia on the development of hypertension in Japanese male workers. Using the annual health examination database of a Japanese telecommunication company, eligible middle-aged male participants in the 1994 health examination were followed up until 1998 or the development of hypertension (either initiation of antihypertensive therapy or a systolic blood pressure ≥140 mmHg and/ or a diastolic blood pressure ≥90 mmHg). The effect of difficulty initiating sleep (DIS) was assessed with a DIS dataset (n=4,794), which included non-DIS (n=4,602) and persistent-DIS (n=192) subjects. That of difficulty maintaining sleep (DMS) was assessed with a DMS dataset (n=4,443), which included non-DMS (n=4,157) and persistent-DMS (n=286) subjects. The incidence of hypertension among persistent-DIS (40.1%; 130.7 per 1,000 person-yr) was significantly higher than that among non-DIS (30.6%; 89.9 per 1,000 person-yr). The incidence of hypertension among persistent-DMS (42.3%; 136.7 per 1,000 person-yr) was significantly higher than that among non-DMS (30.7%; 90.8 per 1,000 person-yr). After adjusting for potential confounding factors (i.e. age, body mass index, smoking, alcohol drinking, and job stress), persistent complaints of DIS and DMS were significantly associated with an increased risk of hypertension (OR=1.96; 95%CI: 1.42-2.70 and OR=1.88; 95%CI: 1.45-2.45, respectively). Persistent insomnia may be a useful predictor of hypertension in Japanese male workers. (J Occup Health 2003; 45: 344-350)
